Subject: fs/9p: Initialize status in v9fs_file_do_lock.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5c4086b8de6989f10ae814f5746604fc44a02a21;p=deliverable%2Flinux.git

fs/9p: Initialize status in v9fs_file_do_lock.

If p9_client_lock_dotl returns an error, status is possibly never filled
but will be used in the following switch.
Initializing it to P9_LOCK_ERROR makes sur we will return an error and
cleanup (and not hit the default case).
